Volume Measurement in Biotech 1 Chapter 3

On all instruments: What is the total volume that can be measured? What is the value of each type of graduation? Start with Graduated Cylinders

L mL µL Review: Metric Measurements and Conversions 1000 92 mL = _________ µL357 µL = _________ mL 0.5 L = _________ mL0.557 mL = _________ µL

Start with 10-mL pipets Show it can be read up or down Show zero, then to tip Explain “TD” Demo green pump and drawing up and dispensing Add 5.60 mL of red solution to tube #1 Add 2.80 mL of red solution and 2.80 mL H 2 0 to tube #2, cap, mix Compare tubes with other techs Use the spec (at 400 nm) to compare them Measuring Small Volumes with Pipets

Repeat with 5-mL pipets Show it can be read up or down Show zero, then to tip Use green pump Using 13x100 mm, add 3.60 mL of red solution to tube #3 Add 1.80 mL of red solution and 1.80 mL H 2 0 to tube #4, cap, mix Compare tubes with other techs Use the spec (at 400 nm) to compare them Measuring Small Volumes with Pipets

Repeat with 2-mL pipets Show it can be read up or down Show zero, then to tip Use blue pump Using 13x100 mm, add 1.90 mL of red solution and 1.90 mL H 2 0 to tube #5, cap, mix Using 13x100 mm, add 0.95 mL of red solution and 2.85 mL H 2 0 to tube #5, cap, mix Compare tubes with other techs Use the spec (at 400 nm) to compare them Measuring Small Volumes with Pipets

Repeat with 1-mL pipets Show it can be read up or down Show zero, then to tip Use blue pump Using 13x100 mm, add 0.90 mL of red solution and 2.70 mL H 2 0 to tube #5, cap, mix Using 13x100 mm, add 0.45 mL of red solution and 3.35 mL H 2 0 to tube #5, cap, mix Compare tubes with other techs Use the spec (at 400 nm) to compare them Measuring Small Volumes with Pipets

Measuring Very Small Volumes with Micropipets Start with any of the micropipets Show how to determine its size and range Show how to hold it so display can be read. Demonstrate how to read it Demonstrate first and second stop Demonstrate how to put a tip on and eject the tip. Demonstrate how to take up and dispense a sample.

Measuring Very Small Volumes with Micropipets Using the P-100 and yellow tips Each partner measures 75.2 µL of one dye into their own 1.7 mL tube. Demonstrate how to compare tube Demonstrate to check it by sucking it up

Measuring Very Small Volumes with Micropipets Using the P-10 and white tips Each partner measures 9.85 µL of one dye into their own 1.7 mL tube. Demonstrate how to compare tube Demonstrate to check it by sucking it up

Measuring Very Small Volumes with Micropipets Using the P-1000 and blue tips Each partner measures 333 µL of one dye into their own 1.7 mL tube. Demonstrate how to compare tube Demonstrate to check it by sucking it up
